What made you stop doing -ing -un?

Greetings,
now I seem to understand most reasons against the system of the Beautiful spring held by Bullshido members/contributors.
Nevertheless, I'm on a kind of sociological quest to find out the EXACT reasons/situation when people realised that they don't like -ing -un, it's not working for them, etc...
So if you please, I'd love to see personal stories (names and locations can be changed to protect the guilty if you insist) like "for years I thought chun makes me a great warrior, then I was invited for a friendly sparring session with a jiu jitsu friend of mine and he tied a knot on me 10 times out of 10 without me being able to land a hit." or something.
Shoot on!
Tonuzaba
P.S.
Welcome to the year 2BOND everybody!

While I appreciate your openness and realize no thread is safe for those the threadstarter imagined to reply, please re-read the name of the thread and my opening posting.
I didn't ask "why did you stop doing that martial art some people on Bullshido think is just as bad as -ing -un"...
There are loads of threads on Bullshido that mix up all of that.
I would hate this thread become such a mix too.
Thank you,
Tonuzaba
